LOUIS YALBLIN, OF CHICAGO, ILLINOIS.

ELECTRIC LIGHT.

Application filed October 18, 1923.

To all whom it may concern:

Be it known that I, LOUIS YABLIN', a citi- Zen of the United States, anda resident of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and'useful Improvements in ElectricLights, of which the following is a specification.

My invention pertains to electric lights, and more particularly toelectric lamps which have a plurality of light sockets that areadjustable.

The main object of the invention is to provide such a light with meansfor moving all the sockets with their light bulbs in unison and foradjusting them at the same inclina tion by engaging and moving any oneof said sockets.

Another object of the invention is to provide a device in which thesockets with their lights are positively adjustable to extend at anequal angle with respect to the shade.

And another object is to provide a device which is durable and efficientin use, and is very economical in construction.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter de scribed and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Fig. 1 is an elevation showing my invention applied to an electric lamp,and supporting the light, bulbs at an equal. inclination with respect tothe shade:

Fig. 2 is a side view partly in section, taken on line 2-2 of Fig. 4;

Fig. 3 is a vertical sectional view on line 33 of Fig.

Fig. 4' is an elevational view of my invention;

Fig. 5 is a vertical sectional view on line 5-5 of Fig. 3': and

Fig. 6 is a horizontal sectional view taken substantially on line 6 6 ofFig. 4.

In the drawings I have illustrated the preferred form of my invention,which comprises a supporting tube or hollow stem 11' to the top ofwhiclris threaded the bight of a yoke 12, and in the upstanding arms orparts of said yoke is mounted a stem 14 by means of its angular sidelugs15 which have their ends upset against said arms, as best shown inFig. 3. A plurality of tubular Serial No. 669,231.

yoke, preferably by passing said members through openings 13 in enlargedportions of the arms 13. as best shown in Fig. 2, and each member has asuitable electric light socket 17 fastened to its outer end forreceiving a suitable bulb 18 therein. Each member 16 is provided with aperipheral opening 19 for receiving the electric conductors 20 whichextend from said sockets 17 through said members 16 and through the tube11.

The tubular members 16 are provided with means for operating them withtheir attached sockets simultaneously and in unison, by engaging andactuating any one of said sockets, and for positively adjusting andsetting said sockets 17 with their lights 18 at the same inclination orangle with respect to the supporting means and the shade. This meanspreferably consists of teeth or ribs 21 which'inter-engage or mesh toforce the members to rotate together, and the members and teeth are soarranged as to tilt or incline the sockets simultaneously to an equaldegree. This means may also be arranged in any other desired manner, themain object being to positively operate al] sockets and lights by merelymoving any one of them, and to positively adjust them to the same degreeofinclination from the vertical position. Fingers 16 are cut out fromthe inner end of each member 16 and bent radially therefrom,substantially at diametrically opposite portions, the upper of saidfingers engaging the top of the opposite member 16 when the sockets 17with the bulbs 18 are substantially swung upward to a horizontalposition, while each lower finger 16" engages beneath the oppositemember 16 when the sockets and lights are adjusted in the verticalposition; these fingers also engaging the arms 13 of the yoke to preventsaid members from being withdrawn from the device.

Covering means for the yoke and the tubular members is provided in theform of a two-part shell, the upper part 22 resting substantially onsaid members by means of a notched flange 23, while the lower part 24 ofthe shell has a similar notched flange 25 which engages in flange 24 andthe notch engages beneath the tubular members 16. The lower end 26 ofthe shell part 24 is turned inward and doubled upon itself'and engagesbeneath the bight of the yoke 12, the bottom of said end 26engaging theupper end of a sleeve 27 which surrounds tube 11 and rests with itslower end on the supporting ring 28 fastened to the lower end of thetube 11, said ring being arranged to mount the device on a suitablepedestal 29 with suitable screws, as shown in Fig. 1, or in any approvedmanner.

Means for mounting a. shade 30 over the lights and other mechanism isprovided in the form of a ring 31 which is threaded or suitably fastenedon stem l t and firmly engages an extension 22 on shell part 22, therebyretaining the shell fastened in posi tion, while a knob 32 is fastenedover said shade on the upper part of the stem 14.

It is apparent from the above disclosure that a convenient andinexpensive device has been provided for positively adjusting all thesockets and lights in a lamp of this kind simultaneously by moving anyone of said lights, and further that said sockets and lights are therebypositively adjusted at an equal and desired angle with respect to saidsupporting means and said shade.

lVlnle I have illustrated and described the preferred form ofconstruction for carrying my intention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, thereforedo not wish to be limited to the precise detailsof construction set forth, but desire to avail myself of such variationsand modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secureby Letters Patent, is:

1. In an electric light, a plurality of parallel members with lightsockets mounted on the outer end of each, and means for moving andadjusting said sockets in unison and at an equal inclination by applyingforce to any one of them.

2 In an electric light, supporting means, a plurality of parallelmembers rotatably mounted on said supporting means and each carrying asocket, and integral engaging means on said members for adjusting saidmembers with their sockets simultaneously by merely engaging andactuating any one of them.

In an electric light, supporting means, members mounted parallel on saidmeans and having light sockets fixed at their outer ends, andinterengaging means fixed on said members to operate said members andsockets simultaneously and adjust said sockets in the same degree but indifferent direc-' tions. 7

4; In an electric light, supporting means, members mounted on said meansand having light sockets fixed at their outer ends, and tooth meansintegral with said members which intermesh for operating all of saidmembers with their socketssimultaneously and adjust said sockets at thesame inclination. j V

14. In an electric light, a supporting tube, a sleeve mounted aroundsaid tube, a yoke mounted on the upper end of said tube, a stem havinglugs fastened in the upstanding arms of said yoke, covering means havinga lower part fastened, between said sleeve and the bight of said yoke,additional covering means mounted on said stem above said yoke, tubularmembers mounted through said covering means and yoke and having each alight socket on its outer end, tooth means on each of said members forrotating them in unison to adjust the lights at equal inclinations andmeans on each member for limiting its rotation.
